Time off work

How much time should I expect to take off work for each of the following?
- I am tentatively having rapid palatal expansion September 14
- and in about 1.5 years I will have upper jaw surgery (one cut to move my entire upper jaw down)

I am a project engineer and my current projects are both in construction. They will be in construction until the end of 2009. The engineer that I keep in the loop has planned his vacation for the last week of September until the 2nd week of October. This is my dilemma. I know the project will go on without me but unexpected challenges always arise when I am not in the office. I also feel that these projects are my babies and I don't want to leave then with just anyone.

Also my 1st wedding anniversary is Oct 1 this year and I would like to be able to enjoy it.

Thanks for your comments.

Starting again

So it's been a long time since I have posted. Here is my update. I had separators once, they where removed and metal bands where added to my bottom teeth. I had to wait for an approval for my surgery before I could have the upper expander or braces in. My OMS finally applied. This time my surgery has been approved. This wed I get the separators for my upper teeth. The wed after that I get my braces. My tentative at surgery date for the pallet expansion is Sept 14th. I had a trip planned for then but I have rescheduled it.
I am so excited and nervous. What advice do you have for me? Was there any receipts that where quick, easy, and really good?


So that is everything in a quick short package.
